• Press .
• Press 9
• Press 9
• Press 9. "0.999" will blink on the primary
LCD with the "CAL" symbol blinking
• Press the ENTER key. "0.999" stays still
and the "CON" symbol starts blinking
• Press the CON key to confirm and the
"CON" symbol will disappear
Note: To quit from the setting mode, press
the CAL key.
This program provides a fast way to perform
the calibration (without going through the "CAL"
procedure) based on the formula:
KNaCl = (CALBUF * (1 + 1.95% (Tp-25)) / Gt
CALBUF = calibrated buffer solution
Gt = measured solution conductivity at TP
Tp = temperature in °C
e.g. The buffer value is 100.0%, but the
meter shows 90.0%, so by changing
the KNaCl to 1.111, the meter will show
100.0% and will be completely cali-
brated.
* calibrated factor value range : 0.5 - 3.5
To revert to normal operation:
• Press the PGM key
• Press 0
• Press the ENTER key.
This program provides a fast way to perform
the calibration (without going through the "CAL"
procedure) based on the formula:
KFERT = (CALBUF * (1 + 3.0% (Tp-25)) / Gt
where:
CALBUF = calibrated buffer solution
Gt = measured solution conductivity at Tp
Tp = temperature in °C
e.g. The buffer value is 1.00 g, but the
meter shows 0.9 g, so by changing the
KFert to 1.111, the meter will then
show 1.00 g and the meter is cali-
brated.
* calibrated factor value range : 0.01 - 1.50
To return to normal operation:
• Press the PGM key
• Press 0
• Press the ENTER key.
PROGRAM # 9
To set or display the NaCl calibration factor
A. To display the NaCl calibration factor:
• Press PGM
• Press 9
• Press ENTER and "P 9" and the current
NaCl calibration factor will respectively
appear on the TEMP. and on the primary
LCD
B. To set the NaCl calibration factor:
e.g. CAL factor 0.999
• Press the CAL key and the current calibra-
tion factor will blink on the primary display.
